+### Integrations with webhooks
+
+You can use {% data variables.product.prodname_code_scanning %} webhooks to build or set up integrations, such as [{% data variables.product.prodname_github_app %}s](/apps/building-github-apps/) or [{% data variables.product.prodname_oauth_app %}s](/apps/building-oauth-apps/), that subscribe to {% data variables.product.prodname_code_scanning %} events in your repository. For example, you could build an integration that creates an issue on {% data variables.product.product_location %} or sends you a Slack notification when a new {% data variables.product.prodname_code_scanning %} alert is added in your repository. For more information, see "[Creating webhooks](/developers/webhooks-and-events/creating-webhooks)" and "[Webhook events and payloads](/developers/webhooks-and-events/webhook-events-and-payloads#code_scanning_alert)."
